Case Study: Government Tender Data Scraping from TUNEPS
The Challenge
Our client, a procurement intelligence and analytics firm, needed to collect government tender data from TUNEPS (Tanzania National e-Procurement System). The goal was to centralize tender listings, deadlines, awarding entities, and bidder information for market analysis and business intelligence. Manual data extraction was slow and missed frequent updates.
Hurdles We Faced
- Authentication & Session Management: TUNEPS required secure login to view complete tender details.
- Dynamic Data Loading: Tender lists and details were fetched via AJAX and paginated APIs.
- Data Volume & Frequency: Thousands of tenders were posted and updated daily.
- Anti-Bot Restrictions: The platform used rate limits and session timeouts.
Our Step-by-Step Approach
Requirement Analysis:
Identified key fields – tender ID, title, category, department, deadline, value, and document links.
Authentication Automation:
Created a secure login handler to authenticate and maintain sessions without manual input.
API Mapping & Extraction:
Reverse-engineered internal API endpoints to extract structured tender data efficiently.
Proxy & Rate Management:
Integrated rotating proxies and adaptive throttling to prevent blocking during bulk extraction.
Data Structuring & Cleaning:
Processed and normalized data into a relational format for easy filtering and analytics.
Scheduling & Updates:
Implemented automated scheduling to keep data refreshed with the latest tenders and awarded contracts.
Results & Impact
- Successfully scraped and centralized thousands of live and archived tenders.
- Delivered a structured dataset ready for analytics, dashboards, and business development teams.
- Enabled near real-time visibility into procurement opportunities.
